Answer: The most commonly mutated gene in people with cancer is p53 or TP53. More than 50% of cancers involve a missing or damaged p53 gene.
The answer is convergent evolution.
<span>A convergent evolution is a process of independent evolution of similar traits in unrelated species. These traits are called analogous structures which are similar in form or function but were not present in the last common ancestor of those species. For example, both birds and bats have wings. However, wings were not present in the last common ancestor of tetrapod to which they belong. They are only similar in function and develop in response to the similar way of life.</span>

Explanation:
Answer:
It has little rain
Explanation:
The classification for deserts on earth is an extreme absence of rainfall. Antarctica reaches below this threshold of water, therefor it can be also classified as a desert
Answer:
A Ligase
B False
C To separate the double‑stranded DNA
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories in order to make millions of copies of a specific sequence of DNA. PCR requires deoxynucleotide triphosphates (dNTPs) to synthesize new copies of the target DNA fragment, a thermostable DNA polymerase that adds nucleotides to new DNA strands, and primers that attach to complementary ends at each DNA strand. PCR has three phases: 1-Denaturation, where the double-stranded DNA molecule is heated to separate it into two single (separated) strands; 2-annealing, where the temperature is lowered in order to allow the primers to attach each DNA strand, and 3- extension, where the temperature is increased (again), and the thermostable DNA polymerase adds the appropriate dNTPs to new DNA strands. In consequence, annealing occurs at the lowest temperature. Moreover, during the denaturation stage, the temperature is increased at 90–95°C in order to denature the DNA strands into single strands.
